The story

CR2032 Replacement Batteries for Self Defense Siren, up close

Your self-defense siren gives you confidence when you're walking alone at night or in unfamiliar places. But that peace of mind depends on one small thing: a working battery. When your device starts to fade or you hear that telltale weakening sound, it's time to swap in a fresh CR2032.

These lithium coin cells slide right into your pocket siren to restore full volume and reliability. The same 3V power source also keeps your TV remotes responding, your bathroom scale accurate, your watch ticking and your key fob unlocking doors. Stock a few extras in your junk drawer so you're never caught without power when you need it.

How it works

Up and running in three steps

  1. 01

    Open the battery compartment

    Locate the battery door on your siren and slide or twist it open according to your device's design.

  2. 02

    Replace the old cell

    Remove the depleted CR2032 and insert the new battery with the correct polarity as marked inside.

  3. 03

    Test and close

    Press the siren button to confirm it's working at full volume, then secure the battery compartment.
